3 Claims. (01. 292-204) This invention relates to improvements inclosure securing devices and pertains particularly to an improved latchfor doors or similar closures.

The primary object of the present invention is to provide an improvedlatch structure designed primarily for use upon barn or shed doors orother heavy types of doors which may be effectively actuated either fromthe inside or the outside of the door and which is designed to 10 allowfor a slight movement of the door under applied pressure whereby thebreaking or otherwise damaging of the holding means is prevented.

Another object of the invention is to provide an improved type ofoscillating latch for barn doors,

shed doors or doors of other structures, which comprises a rigid barmounted for oscillation to operative or inoperative position and alsohaving a slight movement toward or away from the door and adjacent jambwhereby, when the device is applied to a barn for example, theapplication of pressure to the inside of the door by animals within thestructure will be ineffective to damage the latch whereas if a securingmeans of the usual hook and staple type were employed the same wouldprobably be broken or otherwise damaged.

The invention, will be best understood from a consideration of thefollowing detailed descrip-. tion taken in connection with theaccompanying drawing forming part of this specification, with theunderstanding, however, that the invention is not confined to any strictconformity with the showing of the drawing but may be changed ormodified so long as such changes or modifications mark no materialdeparture from the salient features of the invention as expressed in theappended claims.

In the drawing:

Figure 1 is a View in elevation of the latch embodying the presentinvention showing the same applied;

Figure 2 is a sectional View on the line 22 of Figure 1;

Figure 3 is a sectional view on the line 33 of Figure 4 is a sectional'view on the line 44 of Figure 2.

Referring now more particularly to the drawing, wherein like numerals ofreference designate corresponding parts throughout the several views,the numeral l represents a portion of a door jamb while a portion of theadjacent door is indicated by the numeral 2. The jambxportion of thedoor structure is shown as including the usual vertical posts at theinner side of the wall,

adjacent which the front edge of the door 2 positions when the door isclosed.

The latching device embodying the present invention comprises the longflat latch bar 4 which is provided adjacent one end and upon one flatface with the staple 5 while at the opposite end and upon the same facethere is secured the pin 6 which constitutes a means of taking a holdupon the bar for the purpose of oscillating the same in the mannerhereinafter to be described. a 10 Intermediate its ends the bar 4 isprovided with an aperture 1 which is of polygonal cross section asillustrated and passingthrough this aperture is the shaft 8 which is ofa cross sectional design corresponding with the aperture 1 15 so thatrotation or oscillation of the shaft about its long axis willefiectcorresponding oscillation of the latch bar 4.

One end of the shaft 8 is of circular cross section and threaded, asindicated at 9, to receive a 20 nut l0 and encircling the shaft anddisposed between the nut I0 and latch bar 4 is a coil spring H which isconstantly under tension when the device is in use, tending to expand toforce the latch bar and the nut Ill apart. 25

Upon the opposite side of the latch bar 4 from the spring II are the twowashers l2 and i3 and secured to the other end of the shaft 8 isthehandle 14 which, as' shown, has a collar l5 to receive the end of theshaft and this collar car- 30 ries a set screw 16 which engages theshaft 8 to secure the handle thereto. i

In installing the latch, the stud and adjacent portion of the buildingwall which form the jamb for the front edge of the door 2, are provided35 with a circular aperture l1 through which the shaft 8 extends, thewasher I2 being disposed upon the outer side of the jamb and the washerl3 upon the inner side thereof as illustrated. The latch bar 4 isdisposed against the outer face of 40 the wall I so that the end thereofwhich carries the handle 6 may be disposed across the outer face of thedoor 2 when the latch is in door securing position. It will thus be seenthat the handle pin 6 provides a means for oscillating the latch fromthe outside of the door and the handle l4 provides means for oscillatingthe latch through the medium of the shaft 8, from the inside of thestructure.

' On the outer side of the wall I adjacent the end of the latch bar 4which carries the staple, when the latch bar is in horizontal position,there is secured a hasp l8 which may be provided with a suitable slot orrecess to receive the staple 5 55 so that a suitable lock may be appliedto hold the latch bar 4 in door securing position.

From the foregoing description it will be apparent that the latchingdevice herein described will firmly hold the door 2 in closed positionand because of the spring I I will not permit the door to move under theinfluence of light pressures such as might be applied by airdrafts.However, in the event of the application to the inside of the door of aheavy pressure, such as may sometimes be exerted by animals loose withinthe barn to which the device is applied, the door may move outwardlyslightly against the tension of the spring II but as soon as thepressure is removed the spring will exert its influence to return thedoor to closed position.

I claim:

1. A door securing latch comprising a shaft designed to be mounted foraxial oscillation in a wall adjacent to and in transverse relation withthe edge of a door, a bar member having the shaft extended therethrough,the bar being slidable on the shaft but held against rotary motionthereon, spring means encircling the shaft and secured at one endthereto and having its outer end bearing against the bar to force thelatter against the adjacent face of the wall, handle means carried bythe bar at one end, a staple carried by the bar at the other end, and ahandle carried by the shaft upon the end at the side of the wallopposite from the spring.

2. A latch for a door having a jamb or similar structure adjacent anedge thereof, comprising a shaft adapted to extend through the saidstructure for oscillation therein, a handle carried upon an end of theshaft upon the inner side of the door, a bar having the shaft extendingthrough the transverse center thereof and adapted to position againstthe outer side of the door and structure, said bar being movablelongitudinally on the shaft but held against oscillation independentlythereof, a pin projecting from one end of the bar forming an outsidehandle, a hasp engaging staple carried by the bar at its other end, aspring surrounding the shaft between the bar and the end of the shaftremote from the first handle, and means carried by the last mentionedend of the shaft for maintaining said spring under tension.

3. A door securing latch, comprising a shaft designed to be axiallyoscillatably mounted horizontally ina wall adjacent to and in transverserelation with an edge of a door body, a latch bar connected with theshaft on one side of the wall and having movement longitudinally of theshaft but held against rotation thereon, means carried by the latch barfacilitating its oscillation with the shaft, said bar when oscillated toone position extending at one end across the outer face of the door,means on the end of the shaft at the opposite side of the wall from thebar for effecting the oscillation of the shaft, and means resilientlyurging movement of the bar on the shaft toward the wall.
